| **The base of a straight prism is an isosceles triangle with a base of 8 cm and a side side of 5 cm The height of the prism is 10 cm Find the area of the lateral surface of the prism**

The area of the lateral surface of a straight prism can be found as the product of the height of the prism by the perimeter of its base: Sside = h * P.

According to the condition, at the base of this prism lies a triangle with sides equal to 8 cm, 5 cm and 5 cm.This means that the perimeter of the base of the prism is P = 8 + 5 + 5 = 18 cm.

Sside = h * P = 10 * 18 = 180 cm2.
